The present invention relates to apparatus for periodically actuating a perforating tool or tools, with the aid of a control wheel, on the application for printing and other installations.

In known perforating devices of this kind the actuation of the perforating tools and of the feed wheel is eiected during one and the same stroke i an operating member. In such devices difficulties are frequently experienced which 1G cause injury to the sensitive parts of the device;

automatic control of the perforating tools in predetermined periodicity is, therefore, hardly practicable.

The present invention avoids these diiculties by providing that an operating or feed member, is moved to and fro and in one direction of its movement actuates, by means of a coupling member controlled by the control wheel, ay springloaded cutter bolt for moving the perforating tools, whilst in its other direction of movement the operating member advances the control wheel through a predetermined distance. The reciprocating operating member preferably has a driving part and a controlling part, -the latter being provided with a one-way feed device, whilst the former consists of a laterally extending part of the operating member and acts on the cutter bolt through the coupling member, At the same time there is advantageously mounted, above the operating member provided with a driving part and a controlling part, an easily exchangeable member, one part of which consists of a feed or ratchet wheel co-operating with the feed device of the operating member, whilst the other part comprises a control wheel of which the periphery is composed of projecting edges and inverted sur- Y faces.

A sliding member which is adjustable in height by the control wheel and which, in dependence on the position of the control wheel, lies above or in the path of movement of the operating mem ber may advantageously act as the couplingmember between the latter and the cutter bolt that acts on the perforating'cutters. A lever operating the feed member is preferably effective in both of its directions of movement and may engage by means of a rotatably mounted roller a stationary ledger plate, the roller being so mounted as to rotate automatically vduring the feed movements of the lever. The roller is preferably mounted in a recess in the operating lever,

since any colouring matter that may be picked up will then be to a certain extent rubbed off by the rotation of the lroller in its enclosed recess,

or on the ledger plate.

The invention is illustrated by Way of example in the accompanying drawings, in which- Fig. 1 shows a perforating device seen from the side.

Fig, 9 is the same as Fig. 5, except that the ratchet Wheel g and the control wheel It are shown in the position in which the coupling member l is pressed down into its coupling position.

The operating lever. b pivots on an axle c mounted in the casing a.. At the end of the operating lever b which projects through the casing a a roller d is rotatably mounted, for example in a suitable recess (see Figs. 1, 5 and 7). The arm of the operating lever b projecting into the casing actuates the operating bolt e which -is displaceable against a spring p (see Figs. 5 to 9).` 'Ihe operating bolt e has a laterally extending v part m and, at the end facing away from the operating lever b, carries a pawl f which can turn in o-ne direction only.

Above the operating bolt e are mounted, on an axle z', a ratchet Wheel g and a control wheel h which is xed to the ratchet wheel y. The e ratchet Wheel y co-operates with the pawl f of the operating bolt e (see Fig. 7), whilst the control wheel h actuates a coupling member Z which moves alorig a spring lc fixed at one end and bent into a U-shape (see Figs. 5 and 8). The periphf ery of the control wheel h is composed of mutually abutting, curved surfaces which are convex with respect to the axis oi rotation (see Figs. 5 and 7)'.

-Whenone of theginwardly curved surfaces of 5 fil the control wheel h presses against the coupling member i carried by the free end of the spring 7c (see Fig. 5), the coupling member will stay, during any displacement of the operating bolt e, above the part m, and will thus not be carried along with the bolt e, nor will it displace the cutter bolt o. On the other hand, when one of the projecting edges of the control wheel h.l

presses against the spring lc carryingthe coupling member z', the coupling member will, owing to the flexibility of the spring lc, be brought into the.

path of the part m of the control bo-lte and will be carried along by the bolt e1 when actuated by the operating lever D, thus actuating the cutter bolt o.

The method of operation of the novel device is as follows:

When, under the influence of the printing or other installation to the perforating device, the roller d comes into contact with the ledger plate, the lever b will rotate anti-clockwise, thereby displacing the control bolt e, m against the spring p. If now the control wheel h be in the position shown in Fig. 5, in which one of its vinverted surfaces presses against the spring lc,

that is to say, against the coupling member Z carried displaceably on the spring lc the coupling member l will stay above the path of the part m of the operating bolt e, and will thus not be carried along during the displacement of the operating bolt or actuate the cutter' bolt O. The perforating cutters will accordingly stay in their sheaths.` Now, when the roller d of the operating lever b is disengaged from its ledger plate, the spring p will push the operating bolt e, m back into its starting position. At the same time the pawl f, which is effective only on the return path of the operating bolt e, will move the ratchet wheel g, which is fixed to the control wheel h, one step forward.

When, however, during the forward movement of the operating bolt e, m the control wheel h is in the position shown in Fig. 9, one of the projecting edges of the control wheel h presses the spring lc or the coupling member i carried displaceably on the spring k so far down that it comes into the path of movement of the part m of the operating bolt c and will, during the displacement of the operating bolt, be carried along by the part m. This causes the cutter' bolt o tobe displaced so that the perforating cutters emerge against the action of springs tending to hold them in their sheath. When the pressure on the roller d is released, the operating bolt e, m will be brought by the spring p into its starting position and will, thereby, as before by means of the pawl move the ratchet wheel g one step forward. At the same time, owing to the pressure exerted by the springs which tend to hold the perforating cutters in their sheath, the cutter bolt o will likewise be brought back into the starting position, thus also bringing the coupling member Z,

carried displaceably on the spring lc, back into wheel rotatably mounted within the casing, an.

operating element adapted to be moved to and fro by an element of the installation, a springloaded cutter bolt connected to the perforating tools, a coupling member integrally controlled by the control wh-eel and adapted to transfer the movement of the operating element in one direction to the cutter bolt when brought by the control wheel into a working position, and means adapted to advance the control wheel through a predetermined distance during the return movement ofthe operating element.
